Bivans, Glendale, and August Kund, Los Angeles, Calif, assignors to Bivans Corporation, Los Angeles, Calif, a corporation of California Filed Oct. 17, 1963, Ser. No. 316,959 Claims. (Cl. 101-37) The invention relates to a printer for the end flap of cartons, and more particularly, to an improved printer for printing one or more lines of printed matter on the end flaps of cartons while the cartons are conveyed on a carrier through the printing station. The printing station is preferably arranged between a box-forming station, an uprighting station and a stufiing and filling station on the one hand, and a box-closing and discharge station on the other hand.

The end flap, before it is folded and While extending upright from the box on the conveyor, moves between an upright printing cylinder which carries the type, and an impression or backing cylinder. An upright inker or inking cylinder picks up the necessary amount of ink for each impression and conveys it to the type on the printing cylinder as they rotate in contact and in timed relation with the conveyor.

A particular object of the invention is to provide an improved inking arrangement for constantly supplying the inker with a fresh supply of ink. According to the invention, a quantity of ink is stored in a reservoir, means being provided for transferring the ink from the reservoir to a primary roller, preferably of resilient material such as rubber, this roller running in contact with the inking roller, preferably of hard, chrome plated steel, and having an array of ink receiving pockets, or depressions.

The invention provides an applicator in wiping engagement with the primary roller which uniformly distributes the ink from the pockets over the surface of the inking roller.

Preferably, the ink reservoir is arranged below the primary roller. The invention provides improved means including a harmonic motion for elevating the ink from the reservoir with a reciprocating applicator having a period difierent from the period of rotation of the primary roller for applying ink to the primary roller along successively spaced lines.

The invention provides a station for delivering an empty box endwise with the side and end flaps at the outer end thereof closed and with the end flap at the other end of the box projecting outwardly in the plane of the top wall, with an uprighting station for moving the box to upright position, and a conveyor for conveying a succession of upright empty boxes through a printing station where the end flap is printed after the box has been stuffed with a circular, if desired, or filled with its contents, and prior to folding and closing the printed end flap and associated side flaps in the travel on the conveyor to a discharge outlet. The conveyor in question is preferably in horizontal position, operating continuously and in synchronism or timed relation with the apparatus at the various stations.

The invention also provides an improved means for adjusting the pressure between the inking cylinder and the primary roller, and also between the inking cylinder and the printing cylinder. Preferably, this means is in the form of a compression spring urging the respective rollers apart and a screw means for overcoming the spring to adjust the separation to a desired value.

The invention also provides means for adjusting the applicator stroke between the same lower position in the well and a selected upper position on the roller, to ink only that part of the primary roller as required for printing a selected part of the end flap.

Referring in detail to the drawings, the formed empty box may be received at station S1 from a box making machine described and claimed in applicants patents, 2,682,209 and 2,682,210, dated June 29, 1954. The patented box making machine includes a stack of collapsed box 'blanks, indicated at 2, the machine acting to open the box and tuck in the side flaps and the end flap at the outer end 4 thereof. The empty open box 3 is ejected with the other or inner end 5 open and with its side flaps 9 and end flap 6 projecting in the plane of their respective walls.

Means are provided at station S2 for transferring the box from prone position at the outlet of a box forming machine to a vertical position in the conveyor having pairs of spaced leading fingers 16 and lagging fingers 17 engaging the opposite sides of the boxes for conveying the boxes through a leaflet inserter station S3 and along the horizontal bed 18 of the machine in the direction indicated by arrow 26 around return bend 27 through packing station 28 to and along the opposite side of the machine through the printing station S4 and then through the tucking station S5 to the ejecting station S6. The uprighting means includes suction arm 8 having suction head 12 and are described in further detail and claimed 3 in copending application S.N. 316,950 filed Oct. 17, 1963 for Drive for Uprighting Boxes.

The present application discloses a fully automatic machine wherein the patented box making machine operates in timed relation with the conveyor and with the printer and also with apparatus at the other stations along the conveyor.

The conveyor includes a pair of endless chains 14 and 15, see FIG. 4, one of the upper chains 14 having a set of spaced leading fingers 16, the lower chain 15 having a set of cooperating spaced lagging fingers 17, with fingers of each set embracing one of the opposite sides of the box. Preferably the chains 14, 15 are driven by an improved sprocket described and claimed in application S.N. 262,654 referred to above. The drive sprockets are indicated at 11 in FIG. 1 and are preferably angularly adjustable to suit boxes or articles of different widths. Sprockets 11 are driven from shaft 1 by chain 179.

All stations of the machine are driven by the same driver or power source. The power drive for the apparatus at all stations shown .is derived from a power shaft indicated at 1, FIG. 1, and is driven by a suitable motor, not shown. The open box, after being operated on by machine S1 is indicated at 3 and is in prone position, with its outer end 4 closed and its inner end 5 open, the end flap 6 being uppermost and extending in the plane of its wall 7, the side flaps 9 extending in the plane of their respective walls like 10. This box is moved to upright position by the suction arm 8 at the uprighting station S2 as described above.

The sprocket is generally indicated at 11 in FIG. 1 and it includes upper and lower sprockets each driving an endless chain shown at 14 and 15 in FIGS. 3, 4 and 6. The upper chain 14 at spaced intervals carries a leading finger like 16, and the lower chain at corresponding spaced intervals carries a lagging finger 17. The fingers 16 and 17 form one set which engage the opposite sides of the box and propel it along the horizontal fiat bed 18 of the machine. Similar sets of fingers are shown at 19 and 20 in FIG. 1 and at 21, 22. An open box being thus propelled is shown in FIG. 1 at 23, 24, 25, etc., along the conveyor.

On leaving the vicinity of the sprocket 11, the boxes are propelled in a straight line on bed 18 in the direction indicated by arrow 26, and in the opposite direction by the chains at the other side of bed 18. A conventional double sprocket, not shown, is employed at the return bend 27.

In FIG. 1, station S3 indicates a leafiet inserter where a leaflet is inserted in the top open end of each box, as described and claimed in application S.N. 263,854, referred to above. The boxes like 24 and 25 thus each have a leaflet therein. At the other side of the machine in FIG. 1, at the position indicated generally at 28, the desired goods are packed or stuffed by hand, or by automatic means, not shown, into the boxes. On arriving at station S4, the upright end flap is printed as described and claimed in this application.

At station S5, the printed end flap and associated side flaps are tucked in, after folding the end of the end flap, and the closed box is ejected at station S6.

Referring to FIG. 1, the power drive is driven by a motor, not shown, which operates the apparatus at all stations in timed relation, propelling the boxes at uniform speed. This drive operates bevel gears, indicated at 32, which drive a horizontal shaft 33 which carries rotating cams for operating the apparatus at stations S3 and S5. This drive also operates a sprocket 29 which drives chain 30, which drives sprocket 31 at printer station S4, see FIGS. 1 and 3.

Referring to FIG. 3, the sprocket 31 is on a shaft 34 mounted in bearings 35 and 36. Bearing 35 is fixed by screws like 37 to an elevated outer frame member 38. Fixed by screws like 39 and arising from frame member 38 are two posts 40 and 41, hearing 36 being fixed 4 by screws like 42 to an elongated plate 43 fixed by screws like 44 to the top of posts 40 and 41. Sprocket 31 is on one end of shaft 34, the sprocket 45 being on the opposite end and driving chain 46, having an idler take-up 47 having an eccentric mount indicated at 48 for adjusting the amount of take-up.

Chain 46 drives sprocket 49 on the stem 50 of the printing roll 51. Printing roll 51 is inked by the inking roll 52 which in turn is inked by the primary roller 53. Roll 52 has a stem 54 and roll 53 has a stem 55. The stems 50, 54 and 55 are somewhat similar in construction each having a head like 56 at one end and threads like 57 at the opposite end for threaded engagement with a socket like 58 at the top of the roll. Each stem like 50 has a sleeve like 59 having bearing sleeves like 60. The bearing sleeves 60 are mounted in a bracket 61, see also FIG. 2, opposite sides of this bracket appearing in the sectional view in FIG. 4 as this section is taken through the axis of the 3 rolls 51 to 53, bracket 51 having a bearing hole in which the sleeves 60 fit. The stem 54 of roll 52 is similarly mounted in a bearing aperture in bracket 62. Stem 55 of roll 53 has a similar bearing support in the bracket 63.

Referring to FIG. 4, also 2 and 3, sprocket 49 which is driven by chain 46, is fixed to the stem or sleeve 59 of printing roll 51 which also carries a gear 64. Gear 64 has 38 teeth, meshing with gear 65, having 34 teeth, on the stern of inking roll 52 and meshing with gear 66, having 34 teeth, on the stern of primary roll 53. Gears 64, 65 and 66 have a large amount of backlash, permitting gears 64 and 66 to maintain their driving relation while permitting adjustment of the pressure which each of the rolls 51 and 53 exerts on the roll 52. Roll 52 is carried by bracket 62, see FIG. 2, which is fixed in position by screws 67, 68 which extend through strap 72 into bracket 62, the three brackets 61, 62 and 63, at their inner portions, being rectangular in cross section and all of the same height as appears from FIG. 4. Bracket 63, at its inner end, has a hinge support, indicated at 73, on a pin 69, see FIGS. 2 and 3. This pin is press fitted, as indicated at 70 in FIG. 3, at one end in plate 43 and at its opposite end, as indicated at 71, in strap 72 which extends across the inner ends of brackets 61 to 63. Bracket 61 similarly has a hinge support on pin 74, see FIG. 2, similar to pin 69. Bracket 62 is fixed in position by a long bolt 75 which extends into the frame 38 and by a bolt 76 which extends into the plate 43.

Rolls 64 and 66 are each adjustable with respect to roll 65 as follows. Bracket 61, see FIG. 2, has a transverse hole 77, a portion of which is enlarged as shown at 78, to form a spring barrel for a compression spring 79 on bolt 80 which has a head 81 at one side of the bracket and a threaded inner end 81' for thread engagement in a socket 82 in the bracket 62. Spring 79 urges roll 64 away from roll 65 and the screw 80 overcomes this spring and is adjusted to obtain the desired spacing of roll 64 from roll 65. A similar adjusting screw 83 is mounted in the bracket 63 to oppose spring 84, screw 83 also having threaded engagement with the bracket 62, as indicated at 85. Screw 83 has a head 86 as appears in FIGS. 2, 3 and 4.

Bracket 61 has an extension 87 for a backing roller 88, see FIGS. 2, 3 and 6. As shown in FIG. 5, backing roller 88 has an eccentric mount 89 and a clamping screw 90 to adjust the spacing of backing roller 88 from printing roller 51.

FIG. 6 shows a typical open formed box 91, like 3, 23, 24, 25, with its end flap 92, like 6 in FIG. 1, upright in position to pass between the backing roll 88 and the printing roll 51. In FIG. 6, the side flaps 93, 94 are shown closed as this has been accomplished by the side fiap tucker at the tucking station S7, see FIG. 1. In FIG. 6, the boxes like 91 are conveyed in the direction of the arrow 95.

As shown in FIGS. 4 and 6, the primary roll has an outer covering 96 of resilient material such as rubber. As shown in FIG. 14, the steel'inking roller 52 is provided with ink retaining pockets 97, for example, as follows. The surface of the roller is peened with .018 inch diameter balls (less than diameter), to a depth of about .004 inch. The surface is then hard chrome plated. The purpose of this is to cause the ink to cling to the face of the roller, instead of running off. The printing roll 51 is provided with one or more removable lines of type, as well known, and as indicated at 98 in FIGS. 4 and 6.

As shown in FIGS. 2 and 8, suitably mounted on the machine is a rail 101 which slidably supports an ink well 102 having an upright wall 103 having hangers 104 and 105 which support the ink well on the rail. The well 102 can be removed for cleaning purposes, or moved into position below the primary roller, by sliding the well on the rail.

The applicator 100 is driven by a cam 106 on shaft 34, see FIGS. 2 and 3. Cam 106 has a cam follower roller 107 which reciprocates a connecting rod 108, one end of rod 108 being pivoted by bolt 109 and nut 120 at an adjustable position in the slot 110 is a rocker arm 111. Arm 111 has a pivotal support on screw 112 mounted in a bracket extension 125 of plate 43. Bracket extension 125 also carries the rail 101, see FIG. 8, for well 102. The hex shown for 109 and 112 is a socket for a tool. Rocker arm 111 has fixed thereto an outwardly and downwardly extending applicator rod 119 which has fixed on the downwardly extending end 113 thereof a dipper, or applicator, 116 in the form of a short section of tubing 114 of Tygon, or similar plastic material, which is not acted on by the ink. The outer end 117 of tubing 114 is cut on a bias, as shown at 115 in FIG. 4, to provide an upwardly facing shallow, flexible dipper, or applicator, from which the ink spills out as the applicator moves upwardly across the face of the surface of the resilient facing 96 on the roll 53. Tygon is surgical tubing made of polyvinyl chloride, made by US. Stoneware Co. The outer end 117 moves in wiping contact with the surface of the facing 96 and is shown in flexed position at 118 in FIG. 4.

The time required for one revolution of the roll 53 is different from the time for one reciprocation of the applicator 116 whereby the applicator applies the ink to the roller on non-repetitive paths, as indicated in FIG. 7, whereby the ink is applied along successively spaced lines throughout the whole surface of the roller, to substantial- 1y, uniformly ink the inking roller 52. Roller 52 picks up from roller 53 a desired amount of ink depending on the pressure between these rollers, as adjusted by screw 83.

The action of the harmonic motion provided by the rotating roller 53, and the reciprocating applicator 116, will be described in connection with FIGS. 9 to 12. The radius of the slot 110 is the same as the length of connecting rod 108. Through the action of the cam follower 107, the rod 108 is moved a distance D. When the rod 108 is at the limit of its motion to the right, whether the other end of the rod is connected to the top of slot of 110, as shown in FIG. 9, or to the bottom of the slot, as shown in FIG. 11, the applicator 116 dips into the well 102 to receive ink. On the return stroke, corresponding to the setting in FIG. 9, the applicator 116, at the upper limit of its stroke, is only part way up the roller, as shown in FIG. 10, whereas with the setting shown in FIG. 12, the applicator 116 sweeps the full length of the printing roll 51. The height to which the applicator 116 reaches is adjusted by adjusting the bolt 109, see FIG. 13, which fastens the outer end of rod 108 to the rocker arm 111. Bolt 109 has a nut 120 which slidably fits in the slot 110 with a universal coupling 121 between the bolt 109 and the coupling extension 122 of the rod 108 which has a central threaded member 123 held in 6 lengthwise, adjustable position by the nuts indicated at 124.

As shown in FIGS. 2 and 3, the rod section 108 has a coupling extension 126 having a universal connection 127 with a bolt 128 mounted in the end of the cam follower arm 129 on which the cam follower roller 107 is mounted. Arm 129 has a hinge support 130 at one end thereof, its opposite end carrying the bolt 128 which acts as a hanger for spring 131 having an anchor 132. Bolt 128 has a nut 133 which retains the coupling extension 126 in position.

Referring to FIG. 7, the rectangle 135 represents a developed plan view of the surface of the rubber layer 96 while the intersecting lines represent the paths of the applicator end 117 on the surface of the roller. T1 represents the time for one reciprocation of the applicator on the roller assuming that the path starts at the point marked 136. The path 137 leaves the roller at 138 before the roller has made one revolution. The applicator continues its downward stroke, for example, as represented by the dotted line 139 to dip into the well 102. At a later time, represented by T2, the applicator traces the ink path 140. As a result, the ink is applied in crossing paths to approximate a uniform application of ink to the surface of the roller.

The tucker for the side flaps, after the box has been filled, and before arriving at the printer station S4, is indicated by the station S7, FIGS. 1, 15 and 16. The shaft 33 rotates a crank 141 which reciprocates a pitman 142 and connecting rod 143, as indicated by arrow 144. Pitman 142 has fixed thereto a supporting arm, or rod, 145 hav ing a slide bearing support in a rocking bearing 146. The connecting rod 143, at its other end, is hinged as indicated at 147, at a selected position in slot 148 in a rocker arm 149 having a fixed hinge support 150. Arm 149 has fixed thereto a tucker arm 151 the outer end portion 152 of which is somewhat U-shaped with its end 153 extending in the direction of motion of box 154, as shown by the arrow 160. The end 153 engages the lagging side flap 156 and closes it, as shown at 157 in FIG. 16, while the box is traveling whereupon the other side flap rides under and is forced to closed position by the inwardly sloping guide surface 158 on the tucker 134. The end flap 159 remains upright and passes through the printer station S4, as described above.

Referring to FIG. 17, the main body of the printer is the same as-previously described. FIG. 17 shows only that part of the printer which has been modified to -provide for a different back up roller.

To provide for attachment of the back up roller, the extension 87 of the bracket 61 has been altered by cutting off the lower portion of 87 at the line 161. A threaded hole 162 is then added for attaching the bracket 163 of the back up roller assembly 164.

The back up roller 164 consists of, a bracket 163, roller 165, yoke 166, bar 167, compression springs 168 and 169, bolts 170 and 171, stop pin 173 and various washers.

The roller 165 has pins 174 which fit into holes 175 in the yoke 166 to provide for rotation of the roller 165. The yoke is urged outward by compression springs 168 and 169. As best seen in FIG. 19, the bolts and 171 go through holes in the bracket 163 and are threaded into the bar 167. With this arrangement, the bar 167 being against the inner surface 176 of the yoke 166 will hold the yoke in place against the urging of the springs 168 and 169. However, if any matter should become jammed between the printing roller 51 and the back up roller 165, the springs 168 and 169 will give sufiiciently to separate the roller 51 from the back up roller 165 and prevent the type 98 from being damaged. Bolts 170 and 171 will also provide a means of adjustment to give the proper contact and pressure against printed matter passing between the printing roller 51 and the back up roller 165. For example, when the bolt 170 is loosened, the compression springs 168 will urge the roller 165 through its relationship with the yoke 166 in an outward direction. When the bolt 170 is tightened, the threads 177 on the bolt 170 will thread into the threads of 178 in the bar 167 and will pull the roller 165 in an inward direction. The bolt 171 and the spring 169 will operate in an identical manner when the bottom portion of the roller 165 needs adjusting.

Bolt 172 is a means for attaching the back up roller assembly 164 to the bracket 61 of the printer. A pin 173 is press fit into the bracket 163 as shown in FIGS. 17 and 18. The pin 173 will engage the top surface of the extension 87 of the bracket 61 when the back up roller is in its proper relationship with respect to the printing roller 51. The bolt 172 is offset with respect to the center of the bracket 163, as best seen on FIG. 18, so that the bracket may be rotated about the bolt 172 without the pin 173 engaging or contacting any surface within the desired amount of rotation. Shown in FIG. 18 with phantom lines is a rotated position of the bracket 163. The rotation of the bracket 163 will leave an opening and provides easy accessibility to the printing roller 51 in the event that the type on the roller 51 need be changed or replaced.

For details of fingers 16 and 17, reference may be made to FIG. 7 and description of SN. 262,654 referred to above.
